The Company may from time to time appoint such Co-Warrant Agents as it may, in its sole discretion, deem necessary or desirable.

Section 3. Book-Entry Warrant Certificates.

(a) The Warrants shall be issuable in book entry (the “Book-Entry Warrant Certificates”). All of the Warrants shall initially be represented by one or more Book-Entry Warrant Certificates deposited with the Depository Trust Company (“Depository”) and registered in the name of                             , a nominee of the Depository. Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by (i) the Depository or its nominee for each Book-Entry Warrant Certificate or (ii) institutions that have accounts with the Depository (such institution, with respect to a Warrant in its account, a “Participant”).

-2-

(b) If the Depository subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding other arrangements for book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation each Book-Entry Warrant Certificate, and the Company shall instruct the Warrant Agent to deliver to each Holder a Warrant Certificate.

Section 4. Form of Warrant Certificates. The Warrant Certificate, together with the form of election to purchase Common Stock (“Exercise Notice”) and the form of assignment to be printed on the reverse thereof, shall be substantially in the form of Exhibit 1 hereto.

Section 5. Countersignature and Registration. The Warrant Certificates shall be executed on behalf of the Company by its Chairman, its President or a Vice President, either manually or by facsimile signature, and have affixed thereto the Company’s seal or a facsimile thereof which shall be attested by the Secretary or an Assistant Secretary of the Company, either manually or by facsimile signature. The Warrant Certificates shall be countersigned by the Warrant Agent either manually or facsimilise signature and shall not be valid for any purpose unless so countersigned. In case any officer of the Company who shall have signed any of the Warrant Certificates shall cease to be such officer of the Company before countersignature by the Warrant Agent and issuance and delivery by the Company, such Warrant Certificates, nevertheless, may be countersigned by the Warrant Agent, issued and delivered with the same force and effect as though the person who signed such Warrant Certificate had not ceased to be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by any person who, at the actual date of the execution of such Warrant Certificate, shall be a proper officer of the Company to sign such Warrant Certificate, although at the date of the execution of this Warrant Agreement any such person was not such an officer.

The Warrant Agent will keep or cause to be kept, at one of its offices in Canton, Massachusetts, or at the office of one of its agents, books for registration and transfer of the Warrant Certificates issued hereunder. Such books shall show the names and addresses of the respective holders of the Warrant Certificates, the number of warrants evidenced on the face of each of such Warrant Certificate and the date of each of such Warrant Certificate.

-3-

The Warrant Agent will create a special account for the issuance of Warrant Certificates. The Company shall provide an opinion of counsel prior to the Initial Exercise Date to set up reserve of warrants. The opinion shall state that all warrants are:

(1) registered under the Securities Act of 1933, as amended, and all appropriate State securities law filings have been made with respect to the warrants; and

(2) validly issued, fully paid and non-assesable

Section 6. Transfer, Split Up, Combination and Exchange of Warrant Certificates; Mutilated, Destroyed, Lost or Stolen Warrant Certificates. Subject to the provisions of Section 15 hereof and the last sentence of this first paragraph of Section 7 and subject to applicable law, rules or regulations, or any “stop transfer” instructions the Company may give to the Warrant Agent, at any time after the Close of Business on the date hereof, at or prior to the Close of Business on the Expiration Date (as such term is hereinafter defined), any Warrant Certificate or Warrant Certificates or Book-Entry Warrant Certificate or Book-Entry Warrant Certificates may be transferred, split up, combined or exchanged for another Warrant Certificate or Warrant Certificates or Book-Entry Warrant Certificate or Book-Entry Warrant Certificates, entitling the Holder to purchase a like number of shares of Common Stock as the Warrant Certificate or Warrant Certificates or Book-Entry Warrant Certificate or Book-Entry Warrant Certificates surrendered then entitled such holder to purchase. Any Holder desiring to transfer, split up, combine or exchange any Warrant Certificate or Book-Entry Warrant Certificate shall make such request in writing delivered to the Warrant Agent, and shall surrender the Warrant Certificate or Warrant Certificates to be transferred, split up, combined or exchanged at the principal office of the Warrant Agent, provided that no such surrender is applicable to the Holder of a Book-Entry Warrant Certificate. Thereupon the Warrant Agent shall, subject to the last sentence of this first paragraph of Section 7, countersign and deliver to the person entitled thereto a Warrant Certificate or Warrant Certificates, as the case may be, as so requested. The Company may require payment from the Holder of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer, split up, combination or exchange of Warrant Certificates, together with reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental thereto.

Upon receipt by the Company and the Warrant Agent of evidence reasonably satisfactory to them of the loss, theft, destruction or mutilation of a Warrant Certificate, and, in case of loss, theft or destruction, of indemnity or security in customary form and amount which shall include a corporate bond of indemnity satisfactory to the Warrant Agent, and reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental thereto, and upon surrender to the Warrant Agent and cancellation of the Warrant Certificate if mutilated, the Company will make and deliver a new Warrant Certificate of like tenor to the Warrant Agent for delivery to the Holder in lieu of the Warrant Certificate so lost, stolen, destroyed or mutilated.

Section 7. Exercise of Warrants; Exercise Price; Expiration Date.

(a) The Warrants shall be exercisable commencing upon six months from their date of issuance (the “Initial Exercise Date”). The Warrants shall cease to be exercisable and shall terminate and become void, and all rights thereunder and under this Agreement shall cease, at or prior to the Close of Business on the date that is the fifth anniversary of the Initial Exercise Date (the “Expiration Date”). Subject to the foregoing and to Section 8(b) below, the Holder of a Warrant may exercise the Warrant in whole or in part upon surrender of the Warrant Certificate, if required, with the executed Exercise Notice and payment of the Exercise Price, which may be made, at the option of the holder, in cash in United States dollars or by certified or official bank check, to the Warrant Agent at the principal office of the Warrant Agent in Canton, Massachusetts or to the office of one of its agents as may be designated by the Warrant Agent from time to time. In the case of the Holder of a Book-Entry Warrant Certificate, the Holder shall deliver the executed Exercise Notice and the payment of the Exercise Price as described herein. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Warrant Shares to the Holder without a restrictive legend and all of the Warrant Shares are not then registered for resale by Holder into the market at market prices from time to time on an effective registration statement for use on a continuous basis (or the prospectus contained therein is not available for use), then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a certificate for the number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

Upon receipt of an Exercise Notice for a cashless exercise, the Warrant Agent will promptly deliver a copy of the Exercise Notice to the Company to confirm the number of Warrant Shares issuable in connection with the cashless exercise. The Company shall calculate and transmit to the Warrant Agent, and the Warrant Agent shall have no obligation under this section to calculate, the number of Warrant Shares issuable in connection with the cashless exercise.

-5-

(b) Upon receipt of a Warrant Certificate at or prior to the Close of Business on the Expiration Date, with the executed Exercise Notice, accompanied by payment of the Exercise Price for the shares to be purchased and an amount equal to any applicable tax, governmental charge or expense reimbursement referred to in Section 7 in cash, or by certified check or bank draft payable to the order of the Company (or, in the case of the holder of a Book-Entry Warrant Certificate, the delivery of the executed Exercise Notice and the payment of the Exercise Price and any other applicable amounts as set forth herein), the Warrant Agent shall use reasonable efforts to cause the Warrant Shares to be delivered to or upon the order of the Holder of such Warrant, registered in such name or names as may be designated by such holder by the date that is three (3) Business Days after the latest of (A) the delivery to the Warrant Agent of the executed Exercise Notice, (B) surrender of the Warrant Certificate (but only if required herein) and (C) payment of the Exercise Price and other amounts as set forth herein (including by cashless exercise, if permitted) (such date, the “Warrant Share Delivery Date”); provided, however, that the Warrant Agent shall not be liable to the Company or the Holder for any damages arising out of the failure to deliver the Warrant Share by the Warrant Share Delivery Date. If the Warrant Agent fails to deliver to the Holder a certificate or the certificates representing the Warrant Shares (or, as described below, to credit the account of the Holder’s prime broker through the DWAC system) by the Warrant Share Delivery Date, the Holder will have the right to rescind such exercise. Notwithstanding the foregoing, if the Company is then a participant in the Deposit Withdrawal Agent Commission (“DWAC”) system of the Depository and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by holder or (B) the Warrant is being exercised via cashless exercise, the certificates for Warrant Shares shall be transmitted by the Warrant Agent to the Holder by crediting the account of the Holder’s prime broker with the Depository through its DWAC system.

(c) In case the Holder of any Warrant Certificate shall exercise fewer than all Warrants evidenced thereby, a new Warrant Certificate evidencing the number of Warrants equivalent to the number of Warrants remaining unexercised shall be issued by the Warrant Agent to the Holder of such Warrant Certificate or to his duly authorized assigns, subject to the provisions of Sections 7, 8(b) and 15 hereof.

(d) In addition to any other rights available to the Holder, if the Company fails to cause the Warrant Agent to transmit to the Holder a certificate or the certificates representing the Warrant Shares pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss.

-6-

Section 8. Cancellation and Destruction of Warrant Certificates. All Warrant Certificates surrendered for the purpose of exercise, transfer, split up, combination or exchange shall, if surrendered to the Company or to any of its agents, be delivered to the Warrant Agent for cancellation or in canceled form, or, if surrendered to the Warrant Agent, shall be canceled by it, and no Warrant Certificates shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Warrant Agreement. The Company shall deliver to the Warrant Agent for cancellation and retirement, and the Warrant Agent shall so cancel and retire, any other Warrant Certificate purchased or acquired by the Company otherwise than upon the exercise thereof. The Warrant Agent shall deliver all canceled Warrant Certificates to the Company, or shall, at the written request of the Company, destroy such canceled Warrant Certificates, and in such case shall deliver a certificate of destruction thereof to the Company, subject to any applicable law, rule or regulation requiring the Warrant Agent to retain such canceled certificates.

Section 9. Certain Representations; Reservation and Availability of Shares of Common Stock or Cash.

(a) This Agreement has been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery hereof by the Warrant Agent, constitutes a valid and legally binding obligation of the Company enforceable against the Company in accordance with its terms, and the Warrants have been duly authorized, executed and issued by the Company and, assuming due authentication thereof by the Warrant Agent pursuant hereto, constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms and entitled to the benefits hereof; in each case except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally or by general equitable principles (regardless of whether such enforceability is considered in a proceeding in equity or at law).

(b) As of the date hereof, the authorized capital stock of the Company consists of (i) 200,000,000 shares of Common Stock, of which [55,182,174] shares of Common Stock are issued and outstanding,      shares of Common Stock are reserved for issuance upon exercise of the Warrants up to 23,561,356 shares issuable upon the exercise of other outstanding warrants and not more than 4,025,000 shares of Common Stock are reserved for issuance upon exercise of employee stock options and (ii) 40,000,000 shares of preferred stock, $0.0001 par value per share, of which no shares are outstanding. There are no other outstanding obligations, warrants, options or other rights to subscribe for or purchase from the Company any class of capital stock of the Company.

(c) The Company covenants and agrees that it will cause to be reserved and kept available out of its authorized and unissued shares of Common Stock or its authorized and issued shares of Common Stock held in its treasury, free from preemptive rights, the number of shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants.

-7-

(d) The Warrant Agent will create a special account for the issuance of Common Stock upon the exercise of Warrants. The Company shall provide an opinion of counsel prior to the Initial Exercise Date to set up the reserve of Common Stock. The opinion shall state that all shares of Common Stock underlying the Warrants, upon payment of the exercise price, in accordance with the terms of the Warrants are:

(1) registered under the Securities Act of 1933, as amended, and all appropriate State securities law filings have been made with respect to the Common Stock; and

(2) validly issued, fully paid and non-assesable

(e) The Company further covenants and agrees that it will pay when due and payable any and all federal and state transfer taxes and charges which may be payable in respect of the original issuance or delivery of the Warrant Certificates or certificates evidencing Common Stock upon exercise of the Warrants. The Company shall not, however, be required to pay any tax or governmental charge which may be payable in respect of any transfer involved in the transfer or delivery of Warrant Certificates or the issuance or delivery of certificates for Common Stock in a name other than that of the Holder of the Warrant Certificate evidencing Warrants surrendered for exercise or to issue or deliver any certificate for shares of Common Stock upon the exercise of any Warrants until any such tax or governmental charge shall have been paid (any such tax or governmental charge being payable by the holder of such Warrant Certificate at the time of surrender) or until it has been established to the Company’s reasonable satisfaction that no such tax or governmental charge is due.

Section 10. Common Stock Record Date. Each person in whose name any certificate for shares of Common Stock is issued (or to whose prime broker’s account is credited shares of Common Stock through the DWAC system) upon the exercise of Warrants shall for all purposes be deemed to have become the holder of record for the Common Stock represented thereby on, and such certificate shall be dated, the date upon which the Warrant Certificate evidencing such the Company Warrants was duly surrendered (but only if required herein) and payment of the Exercise Price (and any applicable transfer taxes) and submission of the Exercise Notice was made; provided, however, that if the date of such surrender (if applicable), payment and submission is a date upon which the Common Stock transfer books of the Company are closed, such person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding day on which the Common Stock transfer books of the Company are open.

Section 11. Adjustment of Exercise Price, Number of Shares of Common Stock or Number of the Company Warrants. The Exercise Price, the number of shares covered by each Warrant and the number of Warrants outstanding are subject to adjustment from time to time as provided in this Section 11.

-8-

(a) In the event the Company shall at any time after the date of this Agreement (i) declare a dividend on shares of Common Stock payable in shares of any class of capital stock of the Company, (ii) subdivide the outstanding shares of Common Stock into a greater number of shares of Common Stock, (iii) combine the outstanding shares of Common Stock into a smaller number of shares, or (iv) issue any shares of capital stock in a reclassification of shares of the Common Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), then in each case the Exercise Price in effect at that time shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 12(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(b) In the event the Company shall fix a record date for the issuance of rights, options or warrants to all holders of Common Stock (such rights, options or warrants not being available to holders of Warrants) entitling them (for a period expiring within 45 calendar days after such date of issue) to subscribe for or purchase Common Stock (or securities convertible into or exercisable or exchangeable for Common Stock), at a price per share of Common Stock (or having a conversion, exercise or exchange price per share of Common Stock, in the case of a security convertible into or exercisable or exchangeable for Common Stock) less than the VWAP on such record date (or, if there has been no such determination, then the Company must promptly cause such determination to be made as contemplated by the definition of VWAP set forth herein, and any proposed record date must be postponed until after such determination has been made), the Exercise Price in effect at that time shall be multiplied by a fraction, of which the denominator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights, options or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the numerator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights, options or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered (assuming receipt by the Company in full of all consideration payable upon exercise of such rights, options or warrants) would purchase at such VWAP. Such adjustment shall be made whenever such rights, options or warrants are issued, and shall become effective immediately after the record date for the determination of stockholders entitled to receive such rights, options or warrants.

-9-

(c) In the event the Company shall fix a record date for the making of a dividend or distribution to all holders of Common Stock of any evidences of indebtedness or assets or subscription rights or warrants (excluding those referred to in Section 12(a) or (b) or other dividends paid out of retained earnings), then in each such case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record date less the then per share fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of the Common Stock as determined by the Board of Directors in good faith. In either case the adjustments shall be described in a statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.

(d) In the event the Company shall consummate a tender offer for or otherwise repurchase or redeem Common Stock, to the extent that the cash and value of any other consideration included in such payment per share of Common Stock exceeds the VWAP per share of Common Stock on the trading day next succeeding the Expiration Time (as defined below), unless the Company tenders for the Warrants on terms which give effect to such excess consideration, the Exercise Price shall be reduced so that the same shall equal the price determined by multiplying the Exercise Price in effect immediately prior to the last time tenders or repurchases or redemptions may be made pursuant to such tender or repurchase or redemption (the “Expiration Time”) by a fraction of which the numerator shall be the number of shares of Common Stock outstanding (including any tendered, repurchased or redeemed shares) at the Expiration Time multiplied by the VWAP per share of the Common Stock on the trading day next succeeding the Expiration Time, and the denominator shall be the sum of (A) the fair market value of the aggregate consideration payable to shareholders based on the acceptance of all shares validly tendered, repurchased or redeemed and not withdrawn as of the Expiration Time (the shares deemed so accepted being referred to as the “Purchased Shares”) and (B) the product of the number of shares of Common Stock outstanding (less any Purchased Shares) at the Expiration Time and the VWAP per share of the Common Stock on the trading day next succeeding the Expiration Time, such reduction to become effective immediately prior to the opening of business on the day following the Expiration Time. For purposes of this paragraph (d), the value of non cash-consideration shall be as determined in good faith by the Board of Directors of the Company.

(e) Notwithstanding the foregoing paragraphs (a), (b), (c) and (d), no adjustment in the Exercise Price pursuant to such paragraphs shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this Section 12(e) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 10 shall be made to the nearest cent or the nearest hundredth of a share, as the case may be.

-10-

(f) In the event that at any time, as a result of an adjustment made pursuant to Section 11(a), the holder of any Warrant thereafter exercised shall become entitled to receive any shares of capital stock of the Company other than shares of Common Stock, thereafter the number of such other shares so receivable upon exercise of any Warrant shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the shares contained in Section 11(a), (b), (c) and (d), and the provisions of Sections Section 7, 9 and 13 with respect to the shares of Common Stock shall apply on like terms to any such other shares.

(g) All Warrants originally issued by the Company subsequent to any adjustment made to the Exercise Price hereunder shall evidence the right to purchase, at the adjusted Exercise Price, the number of shares of Common Stock purchasable from time to time hereunder upon exercise of the Warrants, all subject to further adjustment as provided herein.

(h) Unless the Company shall have exercised its election as provided in Section 11(i), upon each adjustment of the Exercise Price as a result of the calculations made in Section 11(b), (c) and (d), each Warrant outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Exercise Price, that number of shares (calculated to the nearest hundredth) obtained by (i) multiplying (x) the number of shares covered by a Warrant immediately prior to such adjustment by (y) the Exercise Price in effect immediately prior to such adjustment of the Exercise Price and (ii) dividing the product so obtained by the Exercise Price in effect immediately after such adjustment of the Exercise Price.

(i) The Company may elect on or after the date of any adjustment of the Exercise Price to adjust the number of Warrants, in substitution for any adjustment in the number of shares of Common Stock purchasable upon the exercise of a Warrant. Each of the Warrants outstanding after such adjustment of the number of Warrants shall be exercisable for one share of Common Stock. Each Warrant held of record prior to such adjustment of the number of Warrants shall become that number of Warrants (calculated to the nearest hundredth) obtained by dividing the Exercise Price in effect prior to adjustment of the Exercise Price by the Exercise Price in effect after adjustment of the Exercise Price. The Company shall instruct the Warrant Agent to notify each of the record holders of Warrants of its election to adjust the number of Warrants, indicating the record date for the adjustment, and, if known at the time, the amount of adjustment to be made. Such record date may be the date on which the Exercise Price is adjusted or any day thereafter, but shall be at least 10 days later than the date of the public announcement. Upon each adjustment of the number of Warrants pursuant to this Section 11(i), the Company shall instruct the Warrant Agent to distribute, as promptly as practicable, to holders of record of Warrant Certificates on such record date Warrant Certificates evidencing, subject to Section 14, the additional Warrants to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, instruct the Warrant Agent to distribute to such holders of record in substitution and replacement for the Warrant Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Warrant Certificates evidencing all the Warrants to which such holders shall be entitled after such adjustment. Warrant Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein (and may bear, at the option of the Company, the adjusted Exercise Price) and shall be registered in the names of the holders of record of Warrant Certificates on the record date specified in the public announcement.

-11-

(j) Irrespective of any adjustment or change in the Exercise Price or the number of shares of Common Stock issuable upon the exercise of the Warrants, the Warrant Certificates theretofore and thereafter issued may continue to express the Exercise Price per share and the number of shares which were expressed upon the initial Warrant Certificates issued hereunder.

(k) The Company agrees that it will not, by amendment of its Certificate of Incorporation or through reorganization, consolidation, merger, dissolution or sale of assets, or by any other voluntary act, avoid or seek to avoid the observance or performance of any of the covenants, stipulations or conditions to be observed or performed hereunder by the Company.

(l) In any case in which this Section 11 shall require that an adjustment in the Exercise Price be made effective as of a record date for a specified event, if any holder of a Warrant exercises such Warrant after such record date, the Company may elect to defer, until the occurrence of such event, the issuance of the shares of Common Stock and other capital stock of the Company in excess of the shares of Common Stock and other capital stock of the Company, if any, issuable upon such exercise on the basis of the Exercise Price in effect prior to such adjustment; provided, however, that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder’s right to receive such additional shares and/or other capital securities upon the occurrence of the event requiring such adjustment.

Section 12. Certification of Adjusted Exercise Price or Number of Shares of Common Stock. Whenever the Exercise Price or the number of shares of Common Stock issuable upon the exercise of each Warrant is adjusted as provided in Section 11 or 13, the Company shall (a) promptly prepare a certificate setting forth the Exercise Price of each Warrant as so adjusted, and a brief statement of the facts accounting for such adjustment, (b) promptly file with the Warrant Agent and with each transfer agent for the Common Stock a copy of such certificate and (c) instruct the Warrant Agent to mail a brief summary thereof to each holder of a Warrant Certificate.

Section 13. Reclassification, Consolidation, Purchase, Combination, Sale or Conveyance. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, (v) the Company, directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction. For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. Notwithstanding anything to the contrary, in the event of a Fundamental Transaction that is (1) an all cash transaction, (2) a “Rule 13e-3 transaction” as defined in Rule 13e-3 under the Exchange Act, or (3) a Fundamental Transaction involving a person or entity not traded on a national securities exchange, including, but not limited to, the Nasdaq Global Select Market, the Nasdaq Global Market, or the Nasdaq Capital Market, the Company or any Successor Entity (as defined below) shall, at the Holder’s option, exercisable at any time concurrently with, or within 30 days after, the consummation of the Fundamental Transaction, purchase this Warrant from the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental Transaction. “Black Scholes Value” means the value of this Warrant based on the Black and Scholes Option Pricing Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”) determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Expiration Date. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant in accordance with the provisions of this Section 14 pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the holder of this Warrant, deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein.

-13-

The Company shall instruct the Warrant Agent to mail by first class mail, postage prepaid, to each Holder of a Warrant, written notice of the execution of any such amendment, supplement or agreement. Any supplemented or amended agreement entered into by the successor corporation or transferee shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided for in Section 11 and this Section 13. The Warrant Agent shall be under no responsibility to determine the correctness of any provisions contained in such agreement relating either to the kind or amount of securities or other property receivable upon exercise of warrants or with respect to the method employed and provided therein for any adjustments and shall be entitled to rely upon the provisions contained in any such agreement. The provisions of this Section 14 shall similarly apply to successive reclassifications, changes, consolidations, mergers, sales and conveyances of the kind described above.

Section 14. Fractional Shares of Common Stock

(a) The Company shall not issue fractions of Warrants or distribute Warrant Certificates which evidence fractional Warrants. Whenever any fractional Warrant would otherwise be required to be issued or distributed, the actual issuance or distribution shall reflect a rounding of such fraction to the nearest whole Warrant (up or down), with half Warrants or less being rounded down and fractions in excess of a half of a Warrant being rounded up.

(b) The Company shall not issue fractions of shares of Common Stock upon exercise of Warrants or distribute stock certificates which evidence fractional shares of Common Stock. Whenever any fraction of a share of Common Stock would otherwise be required to be issued or distributed, the actual issuance or distribution made shall reflect a rounding of such fraction to the nearest whole share (up or down), with half shares or less being rounded down and fractions in excess of half of a share being rounded up.

(c) The holder of a Warrant by the acceptance of the Warrant expressly waives his right to receive any fractional Warrant or any fractional share of Common Stock upon exercise of a Warrant.

Section 15. Agreement of Warrant Certificate Holders. Every holder of a Warrant Certificate by accepting the same consents and agrees with the Company and the Warrant Agent and with every other holder of a Warrant Certificate that:

(a) the Warrant Certificates are transferable only on the registry books of the Warrant Agent if surrendered at the principal office of the Warrant Agent, duly endorsed or accompanied by a proper instrument of transfer; and

(b) the Company and the Warrant Agent may deem and treat the person in whose name the Warrant Certificate is registered as the absolute owner thereof and of the Warrants evidenced thereby (notwithstanding any notations of ownership or writing on the Warrant Certificates made by anyone other than the Company or the Warrant Agent) for all purposes whatsoever, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

Section 16. Warrant Certificate Holder Not Deemed a Shareholder. No holder, as such, of any Warrant Certificate shall be entitled to vote, receive dividends or distributions on, or be deemed for any purpose the holder of Common Stock or any other securities of the Company which may at any time be issuable on the exercise of the Warrants represented thereby, nor shall anything contained herein or in any Warrant Certificate be construed to confer upon the holder of any Warrant Certificate, as such, any of the rights of a shareholder of the Company or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting shareholders, or to receive dividends or distributions or subscription rights, or otherwise, until the Warrant or Warrants evidenced by such Warrant Certificate shall have been exercised in accordance with the provisions hereof

Section 17. Concerning the Warrant Agent. The Company agrees to pay to the Warrant Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Warrant Agent, its reasonable expenses and counsel fees and other disbursements incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder.

The Company covenants and agrees to indemnify and to hold the Warrant Agent harmless against any costs, expenses (including reasonable fees of its legal counsel), losses or damages, which may be paid, incurred or suffered by or to which it may become subject, arising from or out of, directly or indirectly, any claims or liability resulting from its actions as Warrant Agent pursuant hereto; provided, that such covenant and agreement does not extend to, and the Warrant Agent shall not be indemnified with respect to, such costs, expenses, losses and damages incurred or suffered by the Warrant Agent as a result of, or arising out of, its gross negligence, bad faith, or willful misconduct.

Promptly after the receipt by the Warrant Agent of notice of any demand or claim or the commencement of any action, suit, proceeding or investigation, the Warrant Agent shall, if a claim in respect thereof is to be made against the Company, notify the Company thereof in writing. The Company shall be entitled to participate as its own expense in the defense of any such claim or proceeding, and, if it so elects at any time after receipt of such notice, it may assume the defense of any suit brought to enforce any such claim or of any other legal action or proceeding. For the purposes of this Section 17, the term “expense or loss” means any amount paid or payable to satisfy any claim, demand, action, suit or proceeding settled with the express written consent of the Warrant Agent, and all reasonable costs and expenses, including, but not limited to, reasonable counsel fees and disbursements, paid or incurred in investigating or defending against any such claim, demand, action, suit, proceeding or investigation.

The Warrant Agent shall be responsible for and shall indemnify and hold the Company harmless from and against any and all losses, damages, costs, charges, counsel fees, payments, expenses and liability arising out of or attributable to the Warrant Agent’s refusal or failure to comply with the terms of this Agreement, or which arise out of Warrant Agent’s negligence or willful misconduct or which arise out of the breach of any representation or warranty of the Warrant Agent hereunder, for which the Warrant Agent is not entitled to indemnification under this Agreement; provided, however, that Warrant Agent’s aggregate liability during any term of this Agreement with respect to, arising from, or arising in connection with this Agreement, or from all services provided or omitted to be provided under this Agreement, whether in contract, or in tort, or otherwise, is limited to, and shall not exceed, the amounts paid under this Agreement by the Company to Warrant Agent as fees and charges, but not including reimbursable expenses.

Promptly after the receipt by the Company of notice of any demand or claim or the commencement of any action, suit, proceeding or investigation, the Company shall, if a claim in respect thereof is to be made against the Warrant Agent, notify the Warrant Agent thereof in writing. The Warrant Agent shall be entitled to participate at its own expense in the defense of any such claim or proceeding, and, if it so elects at any time after receipt of such notice, it may assume the defense of any suit brought to enforce any such claim or of any other legal action or proceeding.

Section 18. Purchase or Consolidation or Change of Name of Warrant Agent. Any corporation into which the Warrant Agent or any successor Warrant Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Warrant Agent or any successor Warrant Agent shall be party, or any corporation succeeding to the corporate trust business of the Warrant Agent or any successor Warrant Agent, shall be the successor to the Warrant Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor Warrant Agent under the provisions of Section 20. In case at the time such successor Warrant Agent shall succeed to the agency created by this Agreement any of the Warrant Certificates shall have been countersigned but not delivered, any such successor Warrant Agent may adopt the countersignature of the predecessor Warrant Agent and deliver such Warrant Certificates so countersigned; and in case at that time any of the Warrant Certificates shall not have been countersigned, any successor Warrant Agent may countersign such Warrant Certificates either in the name of the predecessor Warrant Agent or in the name of the successor Warrant Agent; and in all such cases such Warrant Certificates shall have the full force provided in the Warrant Certificates and in this Agreement.

In case at any time the name of the Warrant Agent shall be changed and at such time any of the Warrant Certificates shall have been countersigned but not delivered, the Warrant Agent may adopt the countersignature under its prior name and deliver Warrant Certificates so countersigned; and in case at that time any of the Warrant Certificates shall not have been countersigned, the Warrant Agent may countersign such Warrant Certificates either in its prior name or in its changed name; and in all such cases such Warrant Certificates shall have the full force provided in the Warrant Certificates and in this Agreement.

Section 19. Duties of Warrant Agent. The Warrant Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Warrant Certificate, by their acceptance thereof, shall be bound:

(a) The Warrant Agent may consult with legal counsel (who may be legal counsel for the Company), and the opinion of such counsel shall be full and complete authorization and protection to the Warrant Agent as to any action taken or omitted by it in good faith and in accordance with such opinion.

-17-

(b) Whenever in the performance of its duties under this Agreement the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by the Chairman, President or any Vice President of the Company and by the Treasurer or any Assistant Treasurer or the Secretary of the Company and delivered to the Warrant Agent; and such certificate shall be full authentication to the Warrant Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate.

(c) The Warrant Agent shall be liable hereunder only for its own gross negligence, bad faith or willful misconduct, pursuant to Section 18, above.

(d) The Warrant Agent shall not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or in the Warrant Certificates (except its countersignature thereof) or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by the Company only.

(e) The Warrant Agent shall not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due execution hereof by the Warrant Agent) or in respect of the validity or execution of any Warrant Certificate (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant Certificate; nor shall it be responsible for the adjustment of the Exercise Price or the making of any change in the number of shares of Common Stock required under the provisions of Section 11 or 13 or responsible for the manner, method or amount of any such change or the ascertaining of the existence of facts that would require any such adjustment or change (except with respect to the exercise of Warrants evidenced by Warrant Certificates after actual notice of any adjustment of the Exercise Price); nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant Certificate or as to whether any shares of Common Stock will, when issued, be duly authorized, validly issued, fully paid and nonassessable.

(f) The Company agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing by the Warrant Agent of the provisions of this Agreement.

(g) The Warrant Agent is hereby authorized to accept instructions with respect to the performance of its duties hereunder from the Chairman or the President or any Vice President or the Secretary of the Company, and to apply to such officers for advice or instructions in connection with its duties, and it shall not be liable and shall be indemnified and held harmless for any action taken or suffered to be taken by it in good faith in accordance with instructions of any such officer, provided Warrant Agent carries out such instructions without gross negligence, bad faith or willful misconduct.

-18-

(h) The Warrant Agent and any shareholder, director, officer or employee of the Warrant Agent may buy, sell or deal in any of the Warrants or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity.

(i) The Warrant Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorney or agents, and the Warrant Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorney or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

Section 20. Change of Warrant Agent. The Warrant Agent may resign and be discharged from its duties under this Agreement upon 30 days’ notice in writing mailed to the Company and to each transfer agent of the Common Stock by registered or certified mail, and to the holders of the Warrant Certificates by first-class mail. The Company may remove the Warrant Agent or any successor Warrant Agent upon 30 days’ notice in writing, mailed to the Warrant Agent or successor Warrant Agent, as the case may be, and to each transfer agent of the Common Stock by registered or certified mail, and to the holders of the Warrant Certificates by first-class mail. If the Warrant Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Warrant Agent or by the holder of a Warrant Certificate (who shall, with such notice, submit his Warrant Certificate for inspection by the Company), then the Holder of any Warrant Certificate may apply to any court of competent jurisdiction for the appointment of a new Warrant Agent. Any successor Warrant Agent, whether appointed by the Company or by such a court, shall be a corporation organized and doing business under the laws of the United States or of a state thereof, in good standing, which is authorized under such laws to exercise corporate trust powers and is subject to supervision or examination by federal or state authority and which has at the time of its appointment as Warrant Agent a combined capital and surplus of at least $50,000,000. After appointment, the successor Warrant Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Warrant Agent without further act or deed; but the predecessor Warrant Agent shall deliver and transfer to the successor Warrant Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof in writing with the predecessor Warrant Agent and each transfer agent of the Common Stock, and mail a notice thereof in writing to the Holders of the Warrant Certificates. However, failure to give any notice provided for in this Section 21, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Warrant Agent or the appointment of the successor Warrant Agent, as the case may be.

Section 21. Issuance of New Warrant Certificates. Notwithstanding any of the provisions of this Agreement or of the Warrants to the contrary, the Company may, at its option, issue new Warrant Certificates evidencing Warrants in such form as may be approved by its Board of Directors to reflect any adjustment or change in the Exercise Price per share and the number or kind or class of shares of stock or other securities or property purchasable under the several Warrant Certificates made in accordance with the provisions of this Agreement.
